Lesson 4

Concept

Change formula: amount paid - cost = change Example: Paid $1.00 for an item costing 63 cents. 100 - 63 = 37 cents change. Counting up method: 63 -> 70 (+7) 70 -> 100 (+30) Total change = 37 cents.

Find the change: 1. Cost 45 cents, pay 1 dollar 2. Cost 78 cents, pay 1 dollar 3. Cost 62 cents, pay 80 cents 4. Cost 39 cents, pay 50 cents
